I'd like to read more details about the options in a filter but I can't seem to find the documentation for it. Specifically I'm interested in the meaning and formats required by "contains any of" and a few of the others.

Any suggestions where to look for fuller documentation of these features?

This pipe symbol does not work as a separator - I can't get the filter to work at all if more than one search term is included on the same line (using "Contains Any Of" or using just "Contains"). Please tell me how to use the filters with more than one term so that I won't have to use a thousand lines to get the filter to work.
